工程项目工期成本质量模糊均衡优化研究

针对不确定环境中工程项目的时间、成本、质量均衡优化问题,在定义目标优属度的基础上,利用模糊多属性群决策效用函数理论,建立了工期、成本、质量模糊均衡优化模型,并基于模糊多模式网络计划技术,采用自适应遗传算法求解得到最满意的决策方案.最后,通过算例验证了模型的合理性和方法的有效性.

Fuzzy Tradeoff Optimization of Time-Cost-Quality in Construction Project

Time,cost and quality are the three main control objects in construction project.The objects are undeterministic because of the undeterministic construction conditions,systematic analysis and fuzzy tradeoff optimization for all objects are very important during engineering management.This paper firstly presents definition of the fuzzy object membership,then presents the fuzzy tradeoff optimization model for time-cost-quality using fuzzy multi-attribute group decision utility function theory.Applying multi-model network planning techniques and self-adaptive genetic algorithms,the most satisfied decision results can be obtained.Finally,a case study is given to verify the effectness of the model and the feasibility of solution method.
